THE NATURE OF ENVIRONMENTAL RISKS
When considering what constitutes an environmental risk in terms of emissions from a site, it can be helpful to view it as consisting of three components-hazard, pathway and receptor. The magnitude of the hazard is related to the nature and quantity of materials and/or process that constitute the risk source. In itself the presence of a hazard might not be significant, as a pathway is required to mean that the hazard can be transported to a target. The nature of the receptor (or target) completes the overall risk profile. A combination of the three factors will determine how significant a risk exists by effectively considering what the probability is of the adverse event and what the consequences would be.
